Can people see everyone who is logged into BuddyPress?

BuddyPress version: I just downloaded the zip and have yet to install it. Version 2.9.2
WordPress version: 4.9.1

I’m about to install BuddyPress on my site and use it in our membership site. My IT guy mentioned that there’s a feature in BuddyPress that allows members who are logged in, to see how many other members are logged in.

Is there a way to turn this feature off? Such that if when we launch our membership, and let’s say we only have a few members in the beginning, they cannot see that there are only 2 members logged into the site?
